Questione giuridica chiave
Whether psychotherapy fees qualify as deductible medical expenses under Art. 9(2)(h) LHID and Art. 4(2) LIPP-V without a medical prescription.
Decisione estratta
Psychotherapy fees are deductible only if they are caused by illness in the statutory sense; in this case, the taxpayer did not prove that requirement because the treatment was not medically prescribed.
Motivazione estratta
The notion of expenses caused by illness requires a direct causal link with restoring or maintaining health. For preventive or personality-development treatments, a medical prescription is a decisive objective criterion; absent such prescription and absent reimbursement by health insurance, the deduction fails.
